and can neil-` Applieation september 26, 193s, seriainazsmao 3 claims.(crise-39) This invention relates to improvements in window screeningdevices; and more particularly to such as are operated automatically bythe operation of the window sash.

. One of the main objects of this invention is to provide an improvedwindow screening device which .is automatically operated by the openingand closing of f the window; and which is readily attachable to thewindow frame and to the sash, and is likewise easily and quicklydetachable therefrom to facilitate cleaning the window sash and sill,and for storing away the device in fall, without operating any screws orsecuring elements or marring. the frame and without the use of anytools. r

Another object of this invention is to provide `an automaticallyoperating screening device which consists of only a `few members thatare readily connectable and mountable inposition in .the window frame,and which are likewise readily removable therefrom, and which preferablyconsists of a pair of guide members detachably connectable `to thewindow jambs, also an operating mechanism including the screen and whichis easily connectable to said guide members and to the window sash, bymerely setting the screen equipped mechanism into place between saidguide members, and is similarly readily removable therefrom. l

A further object of this invention is to provide `such a screeningdevice which comprises a housing carrying a screen therein and providedwith f means whereby the outer end of the screen automatically becomesoperatively connected to the lower bar of the window sash bythe act ofmounting the device in place in the Window frame, so that the screenwill move along with the sash; and in which devicethe screen has itsouter end automatically connected to the` housing when the sash isclosed, and the housing with the screen can then be readily withdrawnfrom the window frame and sash when the `latter is in its closedposition. r

Another object of this invention is to provide such a screening devicecomprising an improved screen roller wherein the parts can be easily puttogether, to save labor and provide for economy in its manufacture.

These and various other obects and advantages are attained with thisinvention, as will become apparent from the following description, takenin connection with the accompanying drawings in whichthis invention isillustrated inits preferred form; it being understood that various otherarrangements and forms -of construction may be resorted to for carryingout the objects I u andpurposes of this invention.

In the drawings:

We have illustrated our invention inthe draw ings in the preferred formof construction, comprising a pair of side members II and I 2 which aredetachably mounted on the pair of jambs or side members I3 of the windowframe; and the screening mechanism I4 which includes a casing or housingI5 carrying therein a roller I6 provided with a screen Il, `all combinedasa unit. Said housing bears on the; lower member orsill i8 di" thewindowframe, and the screen I1 is releasably attached to the lower barla of the window sash I9', so that the mechanism isreadily mountable inposition between the guide members Il and I2 and is readily removabletherefrom. r lower window opening, and can similarly be applied to theupper opening.

l The two side members l! and I 2are economi-` cally constructed fromstrips of sheet metal formed substantially `into the shapes indicated inthe drawings, and each member prerferablyhas its parts made into oneintegral member, tov effect economy in construction; altho each may beformed from one strip of metal or from several strips welded together.l' i l The side member III comprises an attaching portion or bar 20adapted to be attached to jamb I3, and has. spaced guide plates ZI and22 extending atan angle therefrom, and for a sub- It is Shown installed`for screening the stantial distance, so as to guide a substantialmarginal part of the screen in the included chan-'- nel'or space 23therebetween, to take care of variations `from standard widths of windowframes.

v The lower end of plater 22 is bent inward providing a lip 24 to engageupon housin-g I5; while a bracket or plate 25 extends from and isintegral with the lower end part of member I I, adapted to engage oneend of roller i6, and has a lower inturned end or lip 26 toengage underhousing I5,

thus holding one end of said housing between the lips 24 and 26 and saidbracket 25. Said bracket plate 125 has an aperture 21 therein to receivethe round end'portion 28 of the rod 29 which extends thru the roller I6.

The side member I2, like its companion member II, comprises an4attaching portion orbar 30 to be attached to the opposite jamb I3, andincludes spaced guide plates 3| and 32 `extending at an angletherefrom,for guiding a Substantial marginal part of the screen in the includedchannelV 33 therebetween; The lower end of plate 32 is bent inwardproviding a lip 34 to engage upon housing I5, and an integral bracketplate 35 extends i'rom the lower end part of member I 2, adapted toengage the end of roller I6, and has an inturned lower endproviding alip 3S to engage under the housing I5, thereby holdin-g the end Aof thehousing between saidv lips3li` and 36 and said bracket 35; The bracket35 has a slanting slot 31 therein to receive the flat end part 3B of therod 29 of the roller; so that the housing 'with its roller and screencan be readily installed between the sid-e members by sliding part 3Bdownwardly in slot 3l, and thus holding said side members and themechanism in position and preventing any accidental sliding away orwithydrawal of the mechanism.

The bars 23 and 38 of members I and I2 have each a notch or opening Allprovided at the `upper end and have an aperture or opening A lnear thelower end. A screw or headed element 42 and a pin 43 are secured toleachjamb I3, and the members II and l2 can then be readily mounted inposition by simply tilting the members, as indicated in ldot-and-da'shlines at the top of Fig. '3, so that notch Mi engages screw 42, and thelower part of the member is pressed to the jamb i3 to bring pin 43 inaperture 4I, said side member being thus held by the head of said screwv42.l .The housing is then slid into positionbe-y tween said sidemembers, thereby securing said 'members and thev screening mechanism inposition inthe frame, as stated above', andv likewise' facilitating thevquick and easy withdrawal of the entire device in the form of threemembers or units.

i The screening mechanism, `which comprises the casing i and the rollerI5 with the screen I1, is arranged to be installed and removed as a unitfrom the side members II and I2 on the 'window jambs and from the windowsash. The housing has a pairjofcaps 45 on its two ends closing the endsandbeing adjustably mounted kthe widths of the frames; and each capcontains a suitable aperture 48 thru which the end por- 'tions 28 andilproject. 70

The roller i5 is economically constructed from a strip of sheet metalcurved so that its side [edges remain slightly spaced and provide avlongitudinal slot 5i). A pair of heads .or head memt bers 5I are pressedi,into the ends of the roller 7'5 and a similar member 52 is forced intothe intermediate portion thereof, each member having a tongue 53 whichengages in said slot 50, to hold said member against turningy therein.The rod 29 extends thru openings in said members and it has a coilspring 54' thereon having one end secured in the rod and the other endpreferably secured in the intermediate member 52, as best shown in Fig.9. The rollerhas ycleats 55 stamped outward thereon which are hooked tothe inner endet" screen Il and are then bent down onto the'roller tosecure the screen in place thereon, as best shown in4 Fig. 4; and thescreen I'! is thus automatically wound on vand operated by the roller inthe casing, and is also detachable from the cleats.

A reinforcing and attaching member 56 is secured. to the outer end ofthe screen. This member is preferably in the form of a doubled strip ofsheet metal including the two portions 5l' and 58 with ythe latterhaving its lower edge portion 53l turned inward and clampingthe bentedge portion of the outer end of screen I'I therebetween. Securingvelements may further be used for positively pressing and holdingportion 5l against the screen and the bent portion 53', as best shown inFig. l0, to secure the screen positively therein. Said member 56 isprovided with key-slots E! yeach having an enlarged lower portion 5i vadapted tc pass readily over the head E2 of a 'headed 'member 52 whichis mounted on the sash iQ, preferably by securing it to thelcwer'attaching part 63 of a handle S3 fastened on 'the bar iSof the bysuitable means, as best shown in ll. Said member 55 is furtherprovidedwith hooks 65 on its upperV end whichengage` in openings 66 provided inthe upper part'of casing I5, as best shown in Fig. 8. Y

With this construction as disclosed above, the

side members II and i2 can be readily set intoyl place on; the windowjambe i3, and the mechanism I4 can thenbe readily placed in positionbetween said members` ii and I2, to mount the entire device in theproper position. The headed members t2 on the window sash and the slotsG I` on the connecting member 5E are so placed that whenthe sash isclosed the enlarged portions i of said slots will be in line with theheads 62' of said member, so as to enable convenient withdrawal of theoperating mechanism from the window sash and frame. Whenever the sash israised said members t2 will engage inthe narrow upper parts of slots 5Iand will then carry along the attaching member 56 and unrcll the screenfor screening the window opening; and when the sash is fully closed saidheads B2 will again be in line with the enlarged portions E i as statedabove` The hooks 55 engage within openings 55 when the window is closed,so as to bring said enlarged portions iii' in line with said heads 62';butl as the sash is raised and members t2 lift the attaching member 55and the screen, it also lifts the hooks 65 from said openings 6% andfrom the casing; yand will again enter them therein as the window sashis closed. This device can thus be readily removed from the window andframe, by simply lifting said mechanism away from the side members andthen sliding said `members away from the window frame;v andthe devicelikewise can be easily replaced, without the ,use
